Nurcacit

Nanjing Union Rubber Chemicals Brand

Products:23

Chemical Name:2- Mercaptobenzothiazole
Compatible Polymers & Resins:Natural Rubbers (NR)
Functions:Accelerator
Features:Good Stain Resistance, Good Aging Behavior, Fast Production Cycle, Low Temperature Curing

Nurcacit MBT PDR can be used as a fast, non-staining accelerator for both dry rubber and latex applications. Low temperature curing can be achieved by the use of Nurcacit TMTD/TETD or Nurcacit DPG as secondary accelerators. Nurcacit MBT confers excellent aging characteristics to vulcanizates.

Nurcacit MBTS PDR

Chemical Name:2,2′-Dithiobis(benzothiazole)
Compatible Polymers & Resins:Nitrile Butadiene Rubber (NBR), Natural Rubbers (NR)
Functions:Accelerator
Features:Good Stain Resistance, Fast Curing, General Purpose, Scorch Resistant

Nurcacit MBTS PDR gives flat, moderately fast cures in nature and synthetic rubber. Also used in a wide range of general purpose rubbers. Non-staining/non-discoloring in “white” stock; act as a plasticizer/retarder in polychloroprene rubber. Secondary acceleration is usually required for synthetic polymers. Exhibits better scorch safety than MBT.

Nurcacit ZMBT PDR

Chemical Name:Zinc di(benzothiazol-2-yl) disulphide
Functions:Accelerator
Features:Scorch Resistant, High Modulus, Good Compression Set

Nurcacit ZMBT PDR finds its main application in latex where it is used as a primary accelerator in combination with ZDMC or ZDEC. Latex films cured with ZMBT have a markedly higher modulus. Furthermore a better compression set resistance in latex foam can be achieved, without increasing the cure time. ZMBT does not destabilize latex formulations. In dry rubber applications, the performance of ZMBT is almost similar to MBT with slight scorch improvement.

Nurcacit MTT PDR

Chemical Name:3-methylthiazolidine-2-thione
Functions:Accelerator
Compatible Polymers & Resins:Chloroprene Rubber (CR)
Processing Methods:Extrusion, Injection Molding
Features:Good Compression Set, Strong Dispersing Properties, Low Melting Point, High Modulus, Good Aging Behavior

Nurcacit MTT PDR used as vulcanization accelerator for chloroprene rubber, Injection-molded and technical extruded articles, profiles, hoses, seals, mills (rollers), cable sheeting, conveyor-belts based on CR. Possesses good module, age-resistance and advantageous compression set. Nurcacit MTT dispersed perfectly in compounds based on polychloroprene. As a result of its relatively low melting point (about 60 to 70 C), the material usually melts down and disperses without any problems. Because Nurcacit MTT is a powerful accelerator, it is best to incorporate it at the end of the mixing process together with ZnO. Particularly in compounds with a high rubber content, high viscosity or containing large amounts of active carbon black, MTT should be incorporated into the otherwise finished compound while it is being preheated for conversion.

Nurcacit CBS PDR

Chemical Name:N-Cyclohexyl-2-benzothiazolesulfenamide
Compatible Polymers & Resins:Ethylene Propylene Diene Monomer (EPDM)
Functions:Accelerator
Features:Fast Curing, Scorch Resistant, High Modulus

Nurcacit CBS PDR is a primary amino based accelerator giving good scorch safety, a fast cure and good modulus development in a variety of general purpose polymers. It is the most active sulfenamide in EPDM.

Nurcacit TBBS PDR

Chemical Name:N-tert-Butyl-2-benzothiazolesulfenamide
Compatible Polymers & Resins:Butyl Rubber (IIR), Natural Rubbers (NR), Styrene Butadiene Rubber (SBR)
Functions:Accelerator
Features:High Modulus, Fast Curing

Nurcacit TBBS PDR provides fast cure and high modules development in NR SBR BR and blends. Normally used alone or with small quantities of ultra accelerators in tire compounds or industrial rubber products. Can be used to effectively replace MBTS/DPG systems TBBS may give equal modulus to CBS or MBS when used as a 10% lower level.

Nurcacit DCBS PDR

CAS Number:4979-32-2
Functions:Accelerator
Features:Slow Curing, Enhanced Physical Properties

Nurcacit DCBS PDR provide a longer scorch time, longer cure time and lower modulus than CZ TBBS and MBS. Thus will require higher use level for equivalent physical properties; more often used in steel skim compounds for improved and adhesion.

Nurcacit MBS GRS

Chemical Name:N-Oxydiethyl-2-benzthiazolsulfenamid
Functions:Accelerator
Processing Methods:Injection Molding, Transfer Molding
Features:Scorch Resistant

Nurcacit MBS GRS provides extended scorch safety and good green stock storage stability compared to CBS or TBBS. It is recommended for applications where extended scorch safety is required such as thick extrusions. Stock with high loading of furnace blacks such as ISAF and SAF. Its long scorch delay is also advantageous in injection or transfer molding operations.

Nurcacit TMTD PDR

Chemical Name:Tetramethylthiuram disulfide
Compatible Polymers & Resins:Chloroprene Rubber (CR), Ethylene Propylene Diene Monomer (EPDM)
Functions:Accelerator
Features:Good Colorability, Good Aging Behavior, Fast Curing, Scorch Resistant, Good Compression Set, Good Color Stability

Nurcacit TMTD PDR can be used as a single accelerator, as a secondary accelerator or as a sulfur donor in most sulfur-cured elastomers. TMTD is scorch and gives fast cure rates. In sulfur less and EV cure system TMTD produces an excellent vulcanization plateau with good heat aging and compression set resistance. Good color retention is obtaining in non-black vulcanizates. TMTD is a valuable secondary accelerator for EPDM. In the vulcanization of polychloroprene rubber with N,N’-ethylene thiourea, TMTD may be used as a retarder.

Nurcacit TMTM PDR

Chemical Name:Tetramethyl Thiuram Monosulfide
Functions:Accelerator
Compatible Polymers & Resins:Chloroprene Rubber (CR)
Features:Good Color Stability, Fast Curing

Nurcacit TMTM PDR used as a secondary accelerator or as a booster for sulfenamides to achieve faster cure rates. TMTM is distinguished by very good processing safety in comparison with other thiurams. High curing activity and no discoloration. Unlike the thiuram dissulfides. TMTM will not produce cures in the absence of added elemental sulfur. It is an excellent accelerator for polychloroprene in association with DPG and sulpur.

Nurcacit DPTT PDR

Chemical Name:Bis(pentamethylene)thiuram tetrasulfide
Compatible Polymers & Resins:Natural Rubbers (NR), Styrene Butadiene Rubber (SBR), Ethylene Propylene Diene Monomer (EPDM), Nitrile Butadiene Rubber (NBR)
Functions:Accelerator
Features:Strong Dispersing Properties

Nurcacit DPTT PDR is secondary accelerator for NR, SBR, EPDM, and NBR. For rich sulfur content of 28%, it could be used as cure agent. In the system of SBR and NBR, it could be used the primary cure agent. No poison and no pollution. Easily dispersed in rubber system.

Nurcacit TETD PDR

Chemical Name:Disulfiram
Compatible Polymers & Resins:Butyl Rubber (IIR), Natural Rubbers (NR), Ethylene Propylene Diene Monomer (EPDM), Styrene Butadiene Rubber (SBR), Nitrile Butadiene Rubber (NBR)
Functions:Accelerator
Features:Good Color Stability, Strong Dispersing Properties

Nurcacit TETD PDR is the natural rubber, styrene-butadiene rubber, nitrile butadiene rubber, butyl rubber, cis-butadiene rubber and latex’s super accelerator and vulcanizing agent. The active sulfur content is 11%, can be used as the neoprene’s modifier. In the rubber, this product is easy to disperse, does not change color, does not pollute, usually uses in making the electric cable, the rubberized fabric, the rubber shoes, the inner tube, the bright color product and so on.
